Looking at geting a new turbo fitted but just didin't know wot to go for, i have got a 99 classic, the car has already had billet rods and forged pistons and a tek3 re-map, any suggestions as what turbo to fit now????

 

Depends on what aims you have. TD05 is always popular. I have a VF35 off an STi8 on my 99 and have 313 bhp, 300 ib/ft

 

TD05s popular and tough, but by all accounts are not good for std gearbox longevity!!

VF28 from a P1 perhaps?

Ns04

 

It would help to know what your power/torque goals are ?

looking at geting towards 300bhp, alredy been dyno'd at 250bhp, heard a few people raving on about vf34, is the number associated with it the size of the turbo

 

I had similar spec to you on my MY00 before I went for the TD05.
I had 256 bhp on the TD04 (usual supporting mods), changed this for a TD05 and fitted a newage wrx intercooler (non STi) and with a re-map got 320 bhp.

Whatever you go for, anything over 300/300 is playing russian roulette with the gearbox.

 

i have just taken off a vf 34 which r/r at 362bhp excellent turbo for the money much better than the vf35 i taken off beforehand think the td05 16g are a bit better at top end though a bit more pricey for a new unit, you will not be dissapointed with a vf34

 

362 on a vf34 ????????????

was this at well lane ?

 

and 348lbs of torque and i have a graph here if you want to see it .

it was at prosport about 2 months ago.

 

vf34 and vf35 r very very similar, its the boost control thats different,

MAYB your 34 is better than your 35, but iirc the 35 has a broader power band,

and my 35 is very similar 2 my 34.

it all depends on the turbo, as every turbo is different.

eg. my 34 and your 34 r not the same they r 2 separate units.

turbo wise if i were upgrading i would go 4 a sz 49 and when my gearbox lets go i would get a gearset. jus have to go easy on the gearbox until the funds r available.

its not worth spending money on the block if u dont wanna spend in other areas.

my 2 cents.

 

Don't you think a 450bhp turbo is a little overkill, laggy, and expensive, for a guy looking for circa 300bhp, or even 350bhp ?


Mark.

 

I went for a VF35. I ported the wastegate to avoid boost creep and it behaves well. 333bhp and it pulls smoothly to 7K.

I didn't think the VF34 was much different in power terms to the VF35.

the vf34 was a little laggier but much better through high mid to top end revs this turbo would work well at 300bhp and also 350bhp if you decided on any extra future mods

 

cheers guys, sounds like i might be investing in a vf34, wot kind of price would i be looking at, any suggestions for next mods to the engine??

 

you need to tell us what mods you have already , you have internal engine mods so there must be other mods aswell ie exhaust filter etc

 

Lets see your graph then nas!

Been away for a while, i have got billet rods and forged pistions, green panal filter, full ninja exhaust with de-cat, tek 3 re-map and think thats bout it.

 

If circa 350 is your aim you'll be very happy with a VF34, quick spooling and good power delivery across the range. I had one on my RB5. I'd also get some GT spec headers, fuel pump and a remap.

You won't be dissapointed

Just what i wanted to hear guy's

cheers daz, what re-map would you recomend, having a trip to teg sport to have a word with them bout doing some work on my car and see about a vf34.
